IBM Power Ideas Portal

This portal is to open public enhancement requests against IBM Power Systems products, including IBM i. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (

Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Post your ideas
  1. Post an idea.

  2. Get feedback from the IBM team and other customers to refine your idea.

  3. Follow the idea through the IBM Ideas process.

Extend Qc3CalculateHash to be able to use SHA3 (FIPS 202)

We use Qc3CalculateHash API to create xml invoicedata hashes, which are needed for data exchange with the hungarian tax office.
For now we have to use SHA-512 (FIPS 180-2) hashing algorithm, but as of April 1st 2020 the hungarian tax office is changing the requirements to use SHA3-512 (FIPS 202) hashing algorithm which is not included in the Qc3CalculateHash API.

Use Case:

Invoicing application in our ERP system.
Invoices are converted to XML, base64 encoded, hashed with Qc3CalculateHash API and sent via Rest Service.

    The Calculate Hash APIs (QC3CALHA and Qc3CalculateHash) and the Create Algorithm Context APIs (QC3CRTAX and Qc3CreateAlgorithmContext) were updated to support calculating a hash value using the SHA-3 algorithm. Set the "Hash algorithm" field in the ALGD0500 format to one of the following values to request the appropriate variant of the SHA-3 hash algorithm.
    Qc3_SHA3_224 (8)
    Qc3_SHA3_256 (9)
    Qc3_SHA3_384 (11)
    Qc3_SHA3_512 (12)
